BACKBAND HOOK.

Application filed April 14, 1923. Serial No. 632,086.

To all whom it may concern:

Be it known that I, JOHN W. GRIM, a citizen of the United States, and a resident of Columbia, in the county of Richland and State of South Carolina, have invented certain new and useful Improvements in Backband Hooks, of which the following is a specification.

My present invention relates generally to back band hooks utilized in practice for the purpose of connecting the trace chain, and my object is the provision of an improved hook of simple inexpensive form providing for ready adj ustability of the back band and for its effective efficient retention without danger of tearing or unduly wearing the back band, and also one providing for the ready connection of a trace chain in the first instance and the prevention of accidental displacement of such trace chain in use.

With these general objects, the further objects and the resulting advantages of my invention may be more plainly seen and better understood by reference to the following description in connection with the accompanying drawing which forms a part of this specification and in which- Figure 1 is a perspective view illustrating my improved back band hook in adjustable engagement with a portion of the back band,

Figure 2 is a bottom plan view of the body or frame of the hook removed, and

Figure 3 is a central transverse vertical section taken therethrough.

Referring now to these figures I have shown in Figures 1 and 2 a portion of a back band 10 whose lower end is folded inwardly and outwardly around a wedge block 11, the latter having a lower body portion with rounded edges to avoid undue wear of the back band and widely distribute the strain of holding the back band by virtue of the fold, this wedge block having an upper reduced and tapering extension 12 for a purpose which will be presently described.

The body of my improved back band hook is in the form of a rectangular frame 13 the sides and ends of which taper so as to present the larger end of the opening in the frame in a downward direction for the reception of the tapering extension 12 of the wedge block upwardly in said opening, said tapering extension of said wedge block coinciding in length to the width or height of the body frame.

One side 14: of the body or frame 13 has at a central point a tongue-like extension 15 bent outwardly and upwardly from its lower edge to form a trace chain engaging hook proper whose upper free end is curved inwardly and terminates substantially within a cut out portion 16 of the upper edge of the frame side 14 so that with the wedge block 11 out of the frame a trace chain may be easily disposed on the hook 15 and, after the back band has been folded around the wedge block and the latter shifted upwardly into the frame 13 so that its reduced tapering extension snugly interfits said frame for the full width of the latter to bind portions of the back band 10 therein, this tapering extension 12 of the wedge band will at its central point at one side come opposite to the cut out portion 16 of the side 14 of the hook frame and will thus be positioned so that its close proximity to the free end of the hook 15 will prevent accidental displacement of the trace chain from the hook and in fact lock the trace chain thereon against removal without first shifting the wedge block out of the frame.

My improved back band hook is thus of simple construction and is naturally strong and durable and is such that the hook proper stands sufficiently far from the animals side in use to avoid all danger of chafing of the animals side by the trace chains.

I claim:

1. A back band hook including a body in the form of a rectangular frame having tapering walls and forming therein a wedge block receiving space whose larger end opens downwardly, one side of said frame having an outwardly and upwardly curved hook proper and having its upper edge cut away opposite the upper inturned free end of the hook, and a wedge block having a tapering frame entering portion and having an enlarged body portion pendent below the frame when its wedge portion is within the wedge block receiving space of the frame as described.

2. A back band hook including a body in the form of a rectangular frame having tapering walls and forming therein a wedge block receiving space whose larger end opens downwardly, one side of said frame having an outwardly and upwardly curved hook proper and having its upper edge cut away opposite the upper inturned free end of the hook, and a wedge block having a tapering frame entering portion and having an enlarged body portion pendent below the frame when its wedge portion is within the wedge block receiving space of the frame, said frame entering portion of said wedge block extending entirely through the frame in its eifective position whereby a portion thereof extends across the cut out portion of the frame side opposite the said free end of the hook proper.

3. A back band hook consisting of a frame having a hook proper at one side and forming a wedge receiving space therein whose enlarged end opens downwardly, and a wedge block having a tapering outer portion to enter the said frame and having an enlarged body portion pendent below the frame in use and provided with rounded edges for the purpose described.
